Curl commands in python program

I need to make the following curl command within a python program. This trains a classifier.

curl -i --user "{username}":"{password}" -F training_data=@{path_to_file}/weather_data_train.csv -F training_metadata="{\"language\":\"en\",\"name\":\"TutorialClassifier\"}" "https://gateway.watsonplatform.net/natural-language-classifier/api/v1/classifiers"

After that, I need my program to make another curl command which queries the previously trained classifier. This query returns some results that I need my program to be able to access and use

curl --user "{username}":"{password}" "https://gateway.watsonplatform.net/natural-language-classifier/api/v1/classifiers/{classifier_id}"

Just entering these commands manually in the terminal works but I need to automate the process using a python or java program . Thanks for any help!

Have you read through the Requests documentation? That's pretty straightforward. There are several different ways to achieve what you want, but your question is at this point far too broad. - Shawn Mehan

I have done this sort of thing with python. Look at the standard packaged urllib2. I have used this to extract rates from the Eurapean Central Bank:

import urllib2 response = urllib2.urlopen("http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml")

Response now contains an the xml response returned from the ECB.
Other useful modules are urlparse, xml.dom and elementree for xml processing.

I also recommend using Requests.

But if you have working curl commands and you want to access their output for further processing you can use subprocess, e.g.

import subprocess
curl_cmd = "..."
output = subprocess.check_output(curl_cmd)
